ECC (Error Correction Codes) is a method used to detect and correct errors introduced during data storage or transmission. Certain kinds of RAM chips inside a computer implement this technique to correct data errors and are known as ECC Memory. ECC Memory chips are predominantly used in servers rather than in client computers. Memory errors …
Unbuffered memory, or unregistered memory, is memory in which no hardware register exists between a RAM chip and a memory controller. Unbuffered memory is not as stable as buffered memory, but is faster and cheaper to implement. While buffered memory may be necessary in some computer systems, such as high-end corporate servers and workstations, where …
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or …
Read-Only Memory or ROM is an integrated-circuit memory chip that contains configuration data. ROM is commonly called firmware because its programming is fully embedded into the ROM chip. As such, ROM is a hardware and software in one. Because data is fully incorporated at the ROM chip’s manufacture, data stored can neither be erased nor …
NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running from …
EEPROM stands for Electrically Erasable Programmable Read-Only Memory. An EEPROM is like an EPROM chip since it can be written in or programmed more than once. Unlike the EPROM chip, however, an EEPROM chip need not be taken out of the computer or electronic device of which it is part when a new program or …
We all use electronic devices, whether they are mobile phones, computer routers, MP3 players, cable boxes, etc. These electronic devices include hardware, the physical electronic components and software, programs that help these components run effectively. Firmware is a mix of both. Firmware Firmware is usually defined as a type of program that runs within an …
PROM stands for Programmable Read-Only Memory. It was invented by Wen Tsing Chow in 1956. Unlike a ROM chip, a PROM chip comes from the manufacturers devoid of any programming. Programming is done by the end user or the makers of electronic devices which require a permanent data storage device. Since it is cheaper than …
Dual Inline Memory Module or DIMM is a series of Random Access Memory (RAM) chips mounted on a small printed circuit board. The entire circuit collectively forms a memory module. DIMMs are commonly used in personal computers, servers, and high-end workstations. The DIMM makes physical contact with the computer’s data bus through teeth like connectors …
Random-access memory is a type of data storage for computers. Commonly known as the acronym RAM or simply memory, random-access memory details the speed in which data that is stored can be accessed at random. This means that the strength of the RAM determines, at random, how fast a piece of data can be pulled …
